Dataism is an emerging worldview that prioritizes the flow and processing of data above all else, seeing the universe as a system of information streams and positioning data as the ultimate source of meaning. Harari presents Dataism as a possible successor to humanism, arising from the convergence of biology, computer science, and big data analytics. Dataism holds that all organisms, including humans, are essentially algorithms—complex data-processing systems—and that their worth can be measured by their capacity to contribute to information flows. This perspective challenges traditional humanist beliefs in free will and individual consciousness, suggesting that non-conscious algorithms might one day outperform humans in decision-making, creativity, and problem-solving. Harari warns that Dataism could radically reshape society by shifting authority from humans to algorithms, leading people to trust data-driven systems over personal intuition in areas ranging from health and finance to politics and art. If Dataism becomes the dominant ideology, it could redefine ethics, meaning, and purpose around the principle of maximizing data flow, potentially rendering human consciousness irrelevant in the grand scheme of information processing.

Chapter 6 Quotes

The fact remains that humankind is today not only far more powerful than ever, it is also far more peaceful and cooperative. How did humans manage that? How did morality, beauty and even compassion survive and flourish in a world devoid of gods, of heaven and of hell?

Capitalists are, again, quick to give all the credit to the invisible hand of the market. Yet the market’s hand is blind as well as invisible, and by itself could never have saved human society. Indeed, not even a country fair can maintain itself without the helping hand of some god, king or church. If everything is for sale, including the courts and the police, trust evaporates, credit vanishes and business withers. What, then, rescued modern society from collapse? Humankind was salvaged not by the law of supply and demand, but rather by the rise of a new revolutionary religion—humanism.

Chapter 11 Quotes

Dataism declares that the universe consists of data flows, and the value of any phenomenon or entity is determined by its contribution to data processing. Dataism thereby collapses the barrier between animals and machines, and expects electronic algorithms to eventually decipher and outperform biochemical algorithms. You may not agree with the idea that organisms are algorithms, and that giraffes, tomatoes and human beings are just different methods for processing data. But you should know that this is current scientific dogma, and that it is changing our world beyond recognition. Not only individual organisms are seen today as data-processing systems, but also entire societies – such as beehives, bacteria colonies, forests and human cities.

Explanation and Analysis:

Like capitalism, Dataism too began as a neutral scientific theory, but is now mutating into a religion that claims to determine right and wrong. The supreme value of this new religion is ‘information flow’. If life is the movement of information, and if we think that life is good, it follows that we should extend, deepen and spread the flow of information in the universe. According to Dataism, human experiences are not sacred and Homo sapiens isn’t the apex of creation or a precursor of some future Homo deus. Humans are merely tools for creating the Internet-of-All-Things, which may eventually spread out from planet Earth to cover the whole galaxy and even the whole universe. This cosmic data-processing system would be like God. It will be everywhere and will control everything, and humans are destined to merge into it.
